World Cup betting players will see club rivals put their differences aside for the big tournament in South Africa, but in the NHL, there are a couple of players looking to heap pressure on their former teams.

Michael Leighton was drafted by Chicago in 1999 with the 165^th pick, and he had a debut to remember, earning a shutout. Then he was shuttled off to Buffalo, Nashville, Philadelphia and Carolina, bouncing between the minors and the NHL. He ended up back in Philadelphia, and the rest is history: Leighton has stepped up every time the Flyers have needed him to this season in the face of injuries, especially in the postseason with Brian Boucher going down. He has faced the Blackhawks once, stopping 39 of 41 shots in a 3-2 win at home in March.

Patrick Sharp was drafted 95^th by Philadelphia in 2001, but failed to stick with the big team after four teams before he was moved to Chicago. The move has paid off for Sharp, as he has increased his point total in his five years in the Windy City, except for last year when he was injured. Sharp has a goal in four career games against the Flyers, but he's currently third on the Blackhawks in playoff points with 16, anchoring a strong second line with Marian Hossa and Troy Brouwer. You could even argue that if Jonathan Toews wasn't in town, Sharp would be the Chicago captain, that's how much respect he has in the locker room, and he will be out to end the Flyers' betting chances.
